I'm not sure I understand what you mean here. If anything a sponsor should be happy if there is an end goal. Far to many projects feel the need to constantly futz with their product long past when its "done". I think the most people understand this about windows. No one is asking for yet another UI change, or intrusive snooping. Windows could have been done the day they released 64-bit windows XP (or windows7 depending on your politics), and we would have a far better OS, if they had simply laid off 90% of the team leaving the remaining people in a bug fix only maintenance mode.
"In the long term, the philosophy behind Xous is that eventually it should “get good enough”, at which point we should stop futzing with it."
I wished more people would get this.
